IV. PROCEDURES
Preliminary Activity Greeting
Prayer
Checking of Attendance by group
Checking of classroom’s orderliness
Setting of Classroom Standards
A. ELICIT (Access
prior knowledge)
To check the students level of understanding, write a one or two –sentence
description for each of the boxed concepts.
B. ENGAGE (Get the
student’s mind
focused on the
topic)
2. C. EXPLORE
(Provide students
with a common
experience)
Objectives:
1. Illustrate the Lewis Symbol of some common metals and non-metals
2. Show the relationship among the number of valence electrons,
electronegativity and ionization energy.
Procedure:
1. Use Figure 1-3 in filling up the table below.
2. The Lewis symbol is composed of the symbol of elements and dots that
represent the valence electron. Distribute the number of valence electron
in the symbol of elements singly first in the four sides of the symbol
before pairing.
Answer the questions on the blanks provided
Questions:
1. Arrange these elements in increasing order.
a) Valence electrons
b) Electronegativity
c) Ionization energy
2. As the number valence electrons increases, what do you notice of the
electronegativity values and ionization energies of the elements?
3. What kind of element has the higher tendency to give its valence
electrons?Why? .
4. What kind of element has the greatest tendency to attract electron? Why?
D. EXPLAIN (Teach
the concept)
3. E. ELABORATE
(Students apply
the information
learned)
Chemical bonding is one of the most basic fundamentals of chemistry that
explains other concepts such as molecules and reactions. Without it, scientists
wouldn’t be able to explain why atoms are attracted to each other or how
products are formed after a chemical reaction has taken place.
F. EVALUATE (How
well know the
students have
learned the
concepts)
A. Tell if the statement is
correct or not.
1. Metals have less than 4
valence electrons while
non-metals have more
than 4 valence electrons.
2. Nonmetals exhibit lower
electronegativities.
3. Metals have lower
ionization energies.
4. Bromine has seven
valence electrons.
5.Potassium, which is a
non-metal, has only one
valence electron.
B.Write the Lewis symbols
of barium, tellurium, lead,
sulphur, and indium. (Item
nos. 6-10.
G. EXTEND (Deepen
conceptual
understanding
through use in new
content)
V. REMARKS
VI. REFLECTION
A.No. of learners who earned
80% in the evaluation
B.No. of learners who require
additional activities for
remediation
C.Did the lesson work? No. of
learners who have caught up w/
the lesson
D.No. of learners who continue
to require remediation
E.Which of my teaching
strategies worked well? Why did
these work?
F. What difficulties did I
encounter which my principal or
supervisor can help me solve?
G.What innovation or localized
materials did I use/discover
which I wish to share with other
teachers?
